to find Mumia sites galore go here ....type Mumia in the search box....you get a long list... pick one and go to it....highlight the address in the box and 'copy' it (ctrl 'c')...then type this in the message box in Mudcat

[a href=address]click[/a]

except...put angle brackets instead of square brackets ....< & > then erase the word 'address' in the formula and 'paste' (ctrl 'v') the address into that space..(avoids typing errors)....the word 'click' can be replaced by any word or combination of words you want...that is what appears blue and is what you actually click on. The first address in the list is

http://burn.ucsd.edu/~archive/psnlist/1995.Jan/0019.html

putting it in the formula gives

[a href= http://burn.ucsd.edu/~archive/psnlist/1995.Jan/0019.html]click[/a] ...(using square brackets to show what it looks like)

using the angle brackets gives this with the word 'this' substituted for the word 'click'

(I keep a copy of the formula (HTML code) in a little file with others so I don't have to type them each time or remember them..)

there are other threads that tell you how to do this in more detail, along with other tricks...do a forum search on 'html'
