You can edit the main menu by going to the bottom of your themes index.template.php file. There there will be a list of already added link, just follow the same format For further help, take a look at the forum in my signature
Could you explain bit more. I can see this part . echo '<li><a href="', $scripturl, '">' , $txt[103] , '</a></li>'; Code (markup): How to add my own link there. ? .
Do you want to add it to the menubar? The says 'Forum', 'Search' etc? Or elsewhere. Please tell me exactly where you want it A screenshot could prove useful
is this the forum? http://forums.mangaraiders.com/ it may be different then the default index.template.php i tried to download a copy of that theme from SMF to look at that file, but it was corrupted. i found a copy in index.template.php, find // Show the [help] button. echo '<li><a href="', $scripturl, '?action=help">' , $txt[119] , '</a></li>'; Code (markup): add after: // How about an extra button. echo '<li><a href="your_link.com">' , $txt[1190] , '</a></li>'; Code (markup): you'll have to find this txt[119] = 'Help'; Code (markup): in index.english.php and add another line, txt[1190] = 'Help'; Code (markup): change Help to whatever text you want to show
