Well I can't quite believe that it's taken almost a whole year, but I finally found the time to finish off that Ajax Chat app that I started last October! Yes it's hard to believe, but refitting a bathroom, building a sponge and even doing work all have to take priority over the writing of a little hobby project.
Excuses aside (especially that one about sponge building), it's done! And online. And you can play with the finished result here.
I think it manages to cover everything I set out to do, with some embellishments I couldn't resist adding:
Yes I know! Automatic "smilification" and "linkification"! Exciting!
Any problems, please do let me know. Although I doubt I'll have much time to fix anything. Maybe in another year or so?
