Necroposting is basically "bringing a topic back from the dead" and we refer to topics that have not been posted in for a long time (generally longer than one month) as "dead topics".
Flaming is when you are verbally attacking someone (verbally meaning written, as we don't verbally speak on a forum like this - you get the idea). Flaming can be considered insulting a person or their race, gender, ideas, etc. Criticism is sometimes confused as flaming by certain members, however there is a clear distinction. A person that is flaming is meaning it in a harmful way, whilst criticism is generally intended to make a person better.
Trolling is basically egging someone on, or leading them to frustration/wrath. Trolling is not necessarily meaning it in a harmful way (as Flaming does) rather it is more of a hope that the other person will become angered/frustrated and will respond in such a manner as to continue an ongoing battle between the two where the "troll" continues making things worse and the other person continues to become frustrated/angry.
At least, that's a rough idea. There are countless examples of this. =]
Here are a few crude examples (you don't want to do any of the following):
NECROPOSTING: Oh look, I found this topic about something that I really want to talk about, but it's a year old and way past the first page. I think I should just reply to see if anyone cares about it any more. I may also do this if I want to agree with someone's argument that they made a year ago. If I legitimately need help and this year-old topic relates to the problem I'm having, then I must reply to it instead of starting my own topic.
FLAMING: You are stupid if you didn't know this, I hate stupid people who are like you and ask stupid questions like this all the damn time!
TROLLING: Why didn't you search this on Google? I will ask you that instead of being helpful. I will also ask you why your mum never taught you such things. You know your life must suck, because I'm so much better than you for knowing this since I was in like... primary school.
Wow thanks a lot for the help! Oh yeah, there is also another word that I needed help with. Ok, it is pretty much self explanatory but, I wanted to ask just to make sure.
Double post - My best guess: To post right after you have replied or just posted after you posted once.
And I would probably never use any of these things in any forums or anything like that but yes very crude
