What is the procedure?

[Smoo]

Now my husband and I play on P99 thank you it's an absolutely wonderful experience..

My son's would like to play as well and we do let them play on ours but I was wondering if I made a third account for them to share , am I allowed to do that?
My hubby wants his character slots as do I for alts lol.. My question is.. is it ok for my sons to have their own account if My hubby and I already have 2 accounts on Ip exception?

I just want to follow the rules and I couldn't find the info myself..

Thanks again!!
