Ok the download has been updated...

The drop down at the top now shows "1 - 6" instead of "0 - 6" etc

Fixed the capitalization glitch on the word R-LInk

R-link not entered was only being triggered if the entry was exactly 'http://' it should also trigger now if the entry is left empty

While using CURL is significantly faster than fopen, it seems that one big factor affecting speeds is DNS lookup by the webserver. While I could go into explicit detail of how this works.. suffice it to say, if you do not see significant speed improvements when using CURL, it is likely due to the DNS servers your web server is configured to use, and is unfortunately impossible to improve upon with any amount of programming.
