I'm not active too much on Wikipedia and I'll usually edit something when I see something that properly needs to be edited or when I've amassed my own material that I think would be useful to include on a particular page.
I will edit pages on just about anything, and it has been a learning process to say the least. I've always been someone keen on self-improvement so if you wish to raise anything to my attention, feel free to do so on my talk page. Cheers.
