I've searched and searched for a forum program that REQUIRES guests to enter a username before their post is accepted. As it is now with EVERY forum program, if a guest forgets to enter a unique username, the forum automatically names them "Guest." As a result I have a bunch of posts by numerous people named "Guest" and it gets confusing.

I found an old mod for IPB for this, but I doubt it works anymore.

Ask your question here please;

I tried, but it won't register me because I'm not a client, yet. But I don't want to buy the program until I know the mod I need is available. :(

Not sure if the mod is available or not but even if it isn't it sounds like a tiny code-tweak which i am sure if requested over at IPSBeyond it could/would be made very quickly for you :)

Just enable the option that guest posting isn't allowed, thereby requiring everyone who wishes to post to register.

I have filed this as part of a bug report as having had a quick play to find a solution for you i discovered the guest posting feature has a couple of problems.

Thanks, Rob! (w00t)

(I won't be purchasing IPB until this is fixed or I know for sure a mod can be done).
