When used to 'regular' forum software Mudcat is indeed a bit bare and ponderous, with a non-functioning search function and all that.

There's a lot to be said for allowing (a limited) time to edit posts for typos, inserting images, easier to handle link insertion etc. Most forums allow you to see (more) quickly where and how many new posts have been made, how many people are actually reading the thread, which is useful.

It works as it is, yes, but that doesn't mean it can't move with the times and work a lot better.
