i want to know that many people says this is my account storage what that mean and many people says wow how got this sticked what does this mean?

ok ill try to answer this :-

Account storage = a second account that players have to keep spare\random pokemon in that they don't want in there main accounts.

Sticked = when someone makes a thread on the forums that players find helpful\useful it can be sticked at the top of the page so it stays on the first page and doesn't need to be bumped up.
