Why can't my friend become a member?
There is a 100.000 users limit. When that number is reached we stop accepting new members. Accounts inactive for more than 180 days are automatically deleted, so keep trying. (There is no reservation or queuing system, don't ask for that.)
When are accounts auto-pruned?
Accounts are pruned when 180 days have elapsed since the last recorded activity. (the "park feature" has been removed) Also note that we regularly clean out accounts with very low share ratios.
