First of all, I think we need a section here dedicated just to grammar? does anyone else agree?
To the point of the thread. PLS PLS HEP ME! I still cannot figure out when to use either one. I've googled both and read and re-read till i'm almost cross eyed, they both seem to mean the same thing.
I just contacted someone and tweeted asking if they could 'Advice' on an issue? i checked and rechecked before sending it and now it seems i used the wrong one.
