Has anyone else had anything odd happpen with the business of entering to: addresses for PMs?
Yes. And always because I forgot how they formatted their name. So I always go looking for them by other means such as finding their posts in topics I remembered they had participated in or previous PMs I've exchanged with them.
Some other methods:
There's a full list of members:
https://forum.kitz.co.uk/index.php?action=mlist As it's such a long list tricks are often needed to get to the right page. BUR comes just before C so click on the C and he's on the same page.
OR
From the first page of the members list click on the Position column heading to sort the list and as he's a Global Moderator, he's on the first page.
OR
On the members list there's a search for Search for Members tab. Enter just bur and he's the 9th entry in the results
OR
On the forum Home page scroll down looking at the Last Post column to see if he's made a recent post (looking now his name appears against two boards).
