+Background
+ * ST != ST Logging
+ * This distincion is not evident for a newcomer.
+ * The same log personality is applicable for other use-cases than ST.
+ * We need a better name in order to minimize confusion
+
+Parameters to keep in mind
+1. What is it that we are trying to abbreviate. Is it a good full name?
+2. Is the abbreviation easy and convenient to use in documentation?
+3. Is the abbreviation easy to prunounce, work into to sentences, etc.?
+4. Is the abbreviation easily confused with something else?
+
+What are we providing - full names and possible abbreviations?
+ * Something sensible that can replace the CT piggyback hack, where a checksum is inserted into a signed certificate.
+ * Checksum Logging, Checksum Transparency
+ * CL, CT
+ * checksumlog, checksumtrans
+ * sumlog, sumtrans
+ * checklog, checktrans
+ * Signature Logging, Signature Transparency
+ * SL, ST
+ * siglog, sigtrans
+ * sigl
+ * Signed Checksum Logging, Signed Checksum Transparency
+ * SCL, SCT
+ * sigsum
+ * sigsumlog, sigsum-log, sigsuml
+ * sigsumtrans, sigsum-trans, sigsumt
+ * sigcheck
+ * sigchecklog, sigcheck-log
+ * sigchecktrans, sigcheck-trans
+
+[rgdd]
+ * The start of three words feels too verbose for an abbreaviation to be useful.
+ * It might be good if the short version does not contain "log". It makes the abbreaviation more difficult to use in speach and text.
+ * "A siglog log", "siglog logging", etc.
+ * Cf. "a sigtrans log", "sigtrans logging", etc.
+ * Checksum Logging, Checksum Transparency
+ * I am not that worried about someone starting to say "CT" (or mix it up).
+ * I am worried about confusion with Go's checksum database.
+ * "Why do we need another checksum database". Well, things are signed too.
+ * I don't like any of the proposed abbreviations. Not sure why, subjective.
+ * Signature Logging, Signature Transparency
+ * If we talk about System Transparency and abbreaviate it ST, I think it is probable that an unfamiliar reader will mix up the meaning of "S".
+ * Sigstore brands Rekor as "Signature Transparency".
+ * Using the same full name is not helpful for anyone. Big no-go for me.
+ * To be fair Rekor is more about signature transparency than we are. E.g., there are many signature schemes and formats that we will never support.
+ * Signed Checksum Logging, Signed Checksum Transparency
+ * I like this because it is descriptive and distinct
+ * It is consistent with how we talk about the log in text and speach
+ * No other tlog project uses the exact same wordings (as far as I know anyway)
+ * An obvious abbreaviation is SCT. That could lead to confusion.
+ * I think most tlog people would know that "SCT" is not a good idea though.
+ * The short abbreaviation has to be introduced clearly, and be convenient. If that is the case, using SCT as an abbreaviation would not cross your mind?
+ * I tried playing with "sigsum" below.
+ * "Sigsum - a free and open source project that brings transparency to signed checksums".
+ * Repos
+ * sigsum-server-go / sigsum-log-go
+ * ...
+ * irc channel, or channels if we start thinking ahead
+ * #sigsum
+ * #sigsum-dev
+ * #sigsum-meet
+ * #sigsum-{log,server}
+ * #sigsum-witness
+ * ...
+ * Website
+ * sigsum.org

+=== Start of a README.md example ===
+# Sigsum Logging
+_Sigsum_ logging brings transparency to **sig**ned check**sum**s. What a checksum represents is up to you. For example, it could be the cryptographic hash of
+a provenance metadata file](https://security.googleblog.com/2021/06/introducing-slsa-end-to-end-framework.html), a [Firefox binary](https://wiki.mozilla.org/Security/Binary_Transparency), or a text document.
+
+Sigsum logging can be used to:
+1. Discover which checksum signatures were produced by what secret signing keys.
+2. Be sure that everyone observes the same signed checksums.
+==== end of example ===

+ * Decision: "Signed Checksum Logging" (full version)
+ * Decision: "sigsum" (short version, what we use to brand the project)
+ * "A sigsum log, "sigsum logging", etc.
+ * Decision: sigsum.org
+ * Con: we don't get domain locking as with .se
+ * Doesn't affect security of logs though.
+ * Pro: less risk of being perceived as a local project in Sweden
