A lot of blogs have this wrong so I'm going to get it as right as I can! (Theres a bit of ranting in this!).

So this is how it is:
Comment  1 XP
Download  1 XP
View  1 XP
Diamond  5 XP
Favourite  5 XP

YOU DO NOT GET XP FOR UPLOADS!!!!!
This is one of the most annoying things I find wrong with these kinds of blog,
You automatically diamond your own projects when you upload them!

If you delete a submission you lose all xp from it. ( I learnt this the hard way!)

Thanks for reading, hope it helped!
Comment if I got something wrong.
