[Tread]

I don't know how.
What could influence the download limit?
Number of posts (following title, junior, apprentice, senior)
Posts per day.
How long someone is member.
Reputation
Referrals

I don't know my download limit (slow internet). The total number of posts (without posts in deleted threads) you see under the join date. On view profile you can see posts per day and referrals. The reputation are the green dots. I guess that you get one dot added for 100 reputation points. Another guess is that you get more points if some one with a high reputation gives you good points, than someone with very few points. I don't know how much points are added if someone gives you some. I don't know how many gave me points, can only see the last 5.

Reputations points are not given often or easily, as you can see at Member List sorted by reputation. The easiest way to get reputation is to post unseen/unposted legal (not stolen, or else unlegal) pictures or other media. I got nearly all (one time not) points for pictures.
