I currently have these products:

Darkly Theme
A nice theme that works good on my phone also. (I actually thought it was a mobile theme when I got it.)

Conversations Pro
A lot nicer than the standard Inbox/Outbox system. I wish you could allow post editing (despite the confusion it might cause), but it's not a big deal. Supports multiple participants and the converter script worked as expected which is awesome.

I noticed that Conversations Pro doesn't have the larger drag n' drop box provided by Advanced Uploader, but dragging to the smaller "choose file" box works just as well.

Shoutbox
I put this on the bottom of my main page. Has just the right features and doesn't take up much room.

Advanced Uploader
I like this a lot, customized the drag n' drop box with some CSS changes to match my theme better. A lot more user-friendly.

These mods made my forum a lot more modern and usable, thanks for a job well done and reasonable prices also.

Thanks a lot mate, I really appreciate your review
