I am now I proud maker of inivison board mods, so if you guys want to see anything please post it here.
You are now you proud maker of mods? Grammar correcting mod.

The internet isnt for grammar

Hmm...some online battle thiny that has sprites and you fight in real time? Maybe you can connect it with the RPG too. Just eye candy I guess.
The forum is fully functioning and serving its purpose, so you don't really need to add anything to it. Of course, if any new mod will disrupt the functionality of anything in the forum, it should be removed in my opinion.
More idea:
Multi-sigs
Alternating multiple pictures
No need for mod, It's already been done. Just search a little.
Well, Yoshi might want to implement them well this time. Anyways, here's more suggestions. How about a link to the "Scan user" page to "Battle this user" or other action in the RPG? Since if a person presses the "Scan this user" link, it's obvious that they want to see RPG stuff too, so why not?
And maybe we can include our own little messages in the auto-messages for the RPG and stuff, like when you start a battle or donate minerals.
I meant accual mods, not addons.
