Thailog: Yes, I realised my interpretation was a little shoddy and added a note which I'll put back here again: "As for finding threads on an individual talk page — that's a problem of implementation, not of concept."

Signatures &mdash; forums are only really used by a subset of users on each wiki, and usually as a place of serious debate. They're not often found by new users, who are most vulnerable to being sucked in by the "coolness factor" of having a pretty signature. In most cases (other than Central's own support forum) "cool signatures" are generally noticed on user talk pages, because that's where new users usually look first after joining &mdash; they're welcomed there, they become acclimatised there. The idea is that introducing this break in the system would introduce a new cycle where fewer and fewer users believe in the necessity of pretty signatures.

Based on Wikia's previous implementations, I think it's safe to assume that deletion of a thread would appear on the recent changes log. Personally, I don't see the problem here. Deleting a thread currently takes one line on the recent changes. Deleting a thread under this system takes one line on the recent changes.
