First, go to "my settings" at the top of the page and poke around. If you want a wider text area, turn off the tags in "tagging". The "go back to forum" button is still at the bottom of the page, but it's called "message list" or something similar. If you want to quote in a reply, you must hit the "quote" button above the reply box. If you want your old moniker, PM Craig. You might give him some time for this, as I'm sure he's quite busy and not getting much in return. I was able to increase font size with the "bigger" gesture on a mac, or Command plus +. Not sure how it's done on a PC.
Any input or shortcuts from you folks is appreciated.
