I just wanted to point out a few little things I like about this forum.
For starters, you can either embed a photo in your post from a host like Photobucket or Flickr... or you can directly upload your image to the server. That allows some flexibility in how you go about arranging your posts.
There are also options at the top of each topic allowing you to subscribe to your topics via RSS or email. Handy for keeping track of replies!
Another interesting thing is if you click on a member's profile, you are given that member's "blog", which is a compilation of their recent posts in their entirety. I can imagine how useful that will be when dealing with prolific folks like Doowad or Avocado Rabbit!
You can also use standard HTML in your posts. See? I did it! Which means if you want to link to a download of your mix, just use HTML.
As I've mentioned around, I'm still working through all the features here. I'll update this thread as I discover new things.
