If you're talking about PMs on the forum, then messages will stay in the outbox until the recipient has read them.Lurch wrote: 20 Jul 2020 15:21 I dont know if Steve's mailbox is full.

I can't say for what reason he's not read them, but please be patient as I know he's been in demand a lot lately so may have just not been able to get to them yet.
