@anon8189768 I try and pop all the ad hoc forum help in here to make it easier to find/keep it together. 
To embed a link you can use the 
icon in your reply editor’s format bar. That will bring up the link wizard. Simply put the URL in the top box, and the text you want to display in the bottom one. And that will give you something that looks like this in your reply window:
[Tracey Cox Supersex G-Spot Vibrator](Tracey Cox Supersex Powerful Rechargeable G-Spot Vibrator - Lovehoney UK)
But will display like this:
Tracey Cox Supersex G-Spot Vibrator
You can also manually add the [] and () brackets in the right places to get the same result too.
And you can start typing a forum topic title into the URL box instead and that will make some auto-suggestions you can pick from.
