I know you are always looking for things to improve on, so here is a quick list I can think of for the events module:

Start and End dates could have a popup calendar link.
Location details should be changeable. For example, I don't need "country", and I need "zipcode" and "state" to be switched around.

There should be a link to unregister.

Contact info should be able to include a linkable email address, a linkable Yahoo/AIM/MSN/XFire account.

Dates should be changeable. For example, I should be able to post a date as 12/21/05 or Saturday, December 21st, 2005, or any other way.

I think your programming is great, so please take these ideas as ways of making your module even better than it currently is.

Thanks for sharing your thoughts - like it! Unfortunately, thousands of download on the page - no feedback whatsoever. Nice there are some exceptions

Thought about that already, yes. I see if there are available classes I can use so I do not have to do this from scratch. I think I've seen something like this somewhere.

So generally, have some more "dynamic" or even customizeable fields (like in CommunityBuilder). Thought about this as well - gimme some time.

This is already there, once in the event list, once in the event details on the top.

Ok, this is probably the same thing as the above. Just improve the whole damn thing

So, you want to be able to configure the dateformat? Can be done, but needs some time. You're not the first one asking for this.
