My Sent and Inboxes seem to hold 99 or 100 in each...total 198/200 before full?.
Perhaps try sending a bigger donation and see if that helps?.
The login remembering thing is something I've simply gotten used to..
Sometimes it sticks and remembers me for weeks...other times not even an hour?.
The long threads thing (like the 100 pg. Rotting Musclecars) where I need to click through the pages by tens is something I've never resolved?.
I tried changing settings to every seemingly possible way but no differences?.
