Yes links are allowed. We have link tools also that allow you to highlight a word or phrase in a response and make it a link to where you want to point at. The link tools are next to the font options above.
I'm wondering if link shows blank if you have an adblock turned on. We can prove this, rubenray, if you post something with a link in it in reply to this post. I have adblock turned off. I don't need it at this website because I am a paying member and I don't get ads.
OK, I turned off my adblocker and I could see it also. I could see other posters links, but not mine. I am posting on my laptop using Windows 10 and the Chrome browser.
