BBO every now and then surprises us with some bug, which we can not prevent, and often can't find explanation of why it happened. Three months or so ago, it deleted 90% of IAC members - Pam, me and others that use bbo_iac nick kept adding them 1 by 1 as they noticed they lost access to the club.
BUT, for some of them, simple adding would not work, and we have no idea why. Those names had to be added, saved, then deleted and added again, huge nuisance.
Unless we hold tournament that is "open" to all BBO, IAC TDs do not include any enemy list, we just simply restrict access to be exclusive to IAC members, simply because all iac enemies are definately not members. Therefore, there is NO Logical explanation why anyone would not be able enter tournament, but able access IAC room in space of 1 hour. I have no answer why it happened.
With Pokerbids, the problem remained untill yesterday when I removed him from iac member list; added him back, logged of and on, and finaly added his name as personal friend of bbo_iac, which shouldn't matter at all, but solved problems.
Some players, annoyed by messages/mails from bbo_iac block that name, ie mark it as enemy. Or it can happen accidently, as they wanted mark it as friend or neutral, and by mistake clicked on enemy - that wouldn't help signing into the trny hosted by bbo_iac.
And lastly, being invisible when signing up doesn't help either, and if trny starts all invisibles (and their pards) are dropped off, automatically by BBO.
