Until I update the website software to post a link you need to put word a or phrase in your post and then highlight it and select the link tool from the menu and put the web link in it. This sets the link in the background of the word you have chosen such as the visible link. It's annoying but until I can find some dedicated time to the upgrade I won't be able to fix it. Normally it would only take me an hour or two but we are at a major software revision that requires me to update 3 or 4 server components such as php, mysql etc... as well as word press and the forum software all at once. It will take a few hours to do it all and then find out what stopped working on other websites hosted with ours and fix them as well.
