That's Odd!

If it's your round Arrgee, I'll just have a massive Single Malt thanks.

... what's the difference between the "new posts" link and the "Notifications" link?

Additional to PM's and messages from mods etc., I see 'Notifications' inform you when there are replies to topics you're subscribed to and when your posts are quoted by others.

...might be worth adding a line of text that comes up when you click "attachments" making it clear what the max file size is for a photo

Done it!

Meanwhile, I'm still typing away at the very bottom of the page using a text box that isn't white but the same background grey as the borders etc. Which I imagine is why I still can't access emoticons.

OK - let's have another crack at this*.
You're on Windows 10 but I've forgotten which browser you use...
I tried to find out by looking through the site stats. but something caught my eye. Number 1 of January's top 30 referrers (with 89 hits) was this Bing search: American womens arses
It seems your posts are attracting a different kind of connoisseur BP.

Alright Mr P ..... Butt!?

Butt what blouse are you wearing? Something Foxy, Chromy or Edgy?

As Jimi Hendrix said "Foxy Lady"

As you're the only one reporting this issue, I'm guessing it's something unique to your set-up. Could it be caused by a Firefox add on you're using I wonder?
Two things to try. Go to Tools/Add-ons and on the Extensions tab temporarily disable anything you have there to see if this eliminates the behaviour. If not, try doing the same on the Plugins and Services tabs.
The other thing is to test on a different browser, if you have one.

Right this is via Intercourse Explorer and it's typing in the right place t'would also appear the emoticons work and all.

So you're right Mr P I have an add-on in FireFix that doesn't like slots!

It would be interesting to know which add-on is to blame. As I said, you can switch 'em off one by one till you pin it down.
