I can't help you with an answer for your main question but I do have 2 notes for you.
First of all, $60 is roughly 15 blinds at 4NL so you probably want to think again about how will you manage your
bankroll. I can understand that you just joined the site and want to see how things work before you deposit but then you should probably play 2NL.
Regarding the loose play made by your opponents, you can only make use of this and get a lot more value for your winning hands. But you must be really careful because having more than an opponent will require you to calculate the ranges for each of them and also take into consideration that the hand has a lot less burned cards.
Good luck on the new room!
