Only posts are subject to the censor. All other replacements with "clam" were done manually.
Thus, the news ticker was as simple as typing "lemmings".
And I assure you all smilies (as well as the read/unread posts icons on the main page) were replaced; however your browser might have cached the usual images. A forced refresh will fix that right up.
As a brief list of what was changed, in case anyone missed anything:
> News ticker: Entirely replaced with clams "fading" in and out and Clam-related messages.
> Board title: Changed to "Clams Forums"
> Board logo: Changed to match the above, though this said "Clam Forums" instead
> Subforum titles / descriptions: Changed "Lemmings" or "Lems" etc to "Clams"
> Read/unread topics icon: Changed to a semi-transparent clam and a solid clam respectively
> Userlevel titles: Admin, Global Mod and Mod changed to "Clamministrator" and "(Global) Clamerator"
> Smileys: All of them replaced with clams. Except those that were already clams, and nothing else. Which is pretty much just the clam smiley.
> Word filter: Word filter was turned on, with "Lemmings" and "Lems" being changed to "Clams" (and similar for their singular equivalents). "(Neo)Lemmix" also became "(Neo)Clammix", "(Super)Lemmini" became "(Super)Clammini", and several recently-discussed level packs names were also put on the filter, including GigaLems > GigaClams, MobiLems > MobiClams, and NepsterLems > NepsterClams - it actually appears Nepster already had this last idea as his post actually says NepsterClams, rather than just being hit by the censor.
As a slight spinoff, I also made references to this in two of the Lemmings-related youtube videos I uploaded yesterday.
A GigaLems video has me saying "Have a Clammy day" instead of "Have a good day" at the end; while a Lemmings Plus video ends with a chant of "Clam people, Clam people, Clam people".
Hope you enjoyed it, and didn't find it too inconvenient.
[edit: dammit, I did it again. Somehow accidentally editing someone else's post instead of replying to it. One downside to being admin. --ccexplore]
