If I may add my own two cents(even though I haven't really been active lately);

6.) Please finish a RPG before starting another one. If you are currently participating in a RPG and wish to participate in another, please announce that you are officially leaving, or wait until it is finished before starting the new one.
I can understand the reasoning behind this rule, in not wanting to get players overwhelmed, but in my opinion, it's the players responsibility to make sure they don't over-commit. Each and every person has a different schedule and things they do, thus different amounts of free time. This rule as-is (since you did suggest altering it), is unfair to people who are able to manage more than one role-play perfectly fine. If it becomes a problem for an individual to manage what they have taken on and hinders a roleplay, then Rule 4--

4.) If, for any reason, you'd wish to not participate any further in an established RPG, then please contact the GM so he or she will know, and is able to recast the role(s) you've taken on. If a participant is not able to contact the GM, or doesn't post regarding their role(s) within a set time, the GM has authority to recast the role(s) as he or she sees fit.
--pretty much can take care of that problem.
Plenty of people are able to do more than one role-play at once, of course part of that depends on how demanding the role-plays they are participating in are, but if the person isn't able to handle the activity, it should be between the specific individual(s) and the GM(s).
If rule six has
to be a rule, I think three should be the limit.
Note that I'm only active in one role-play at the moment because I don't want to over-commit myself or hinder things, so I wouldn't really be affected by this rule currently, but it is not fair as is. Like I said, I think three is a reasonable limit. Some may not be able to do three at a time, but I think part of it should be left up to the player to decide.
tl;dr, I think if you have to set a limit here, don't make it such a low one. People should also be capable of placing limits themselves if they need to, and if not GM's can take care of it.
