It is just a suggestion but I think it would be nice to show the statistics of OGS in the main menu or at the bottom of the page.
I would make appear
nb of current players
nb of current games with the separation blitz/live/correspondence
Countries (bar plot)
Level of players (Bar plot or line chart)
(… partial list)
Otherwise maybe you could add some information in the homepage, as "Friday with whu98 come back the xxth of Setpember, date - hour - be there !"
Or annouce the next live retransmission (when there will be) or big tournament
