Those two are part of the skin, so not editable by me, and no developer is available at the moment to investigate the possibility. I will not this issue down as one to consider at the sprint in early June.
ok. one more question: are the developers are volunteers so that everyone can contribute? Since I'm almost a 3rd yr computer science student and have set up a few websites and have a background of php in which the MediaWiki is written in. So I'm here if needed.
You are most definitely needed. Neverendingo is our sysop, and he needs php-skilled people to help in various areas. Probably you would need to set up your own mediawiki site to experiment on, then take a copy of our skin. When you think you have the solution it should be tested on our sandbox, after which neverendingo would apply it to the actual skin. You should contact kde-www, either by email mailto:"kde-www" <firstname.lastname@example.org> or on IRC, channel #kde-www.
