Another tip I posted elsewhere.
I fluked this one. I opened up the web site I wanted to link to my post. Tap and hold on the address until the bubble comes up to select all. Tap that then go back to your forum post and tap and hold until the bubble comes up to say paste. there is probably another way to do it. Maybe ten ways but I found this one easy. Aslo go to you tube and there is sure to be about 8,000 people showing you "how to" anything.
Also you may have missed my post about using the Atomic Web browser instead of Safari if the forum page is mucking up as mine does on the iPad with all the emoticons dancing about the page. Much lcleaner and clearer on Atomic Web which is a free download.
I also have the "Dummies" book if anyone has a question that can be answered from that.
