maybe change the text color for stand alone events opposed to the league events? Like red for standalone standard blue for league, or any other combo. Just a thought =)
*bump* Just got another suggestion and I thought I'd post it here. LXCC runs weekly events but we have off-weeks after every 3 races. Would it be possible that when you make a weekly event you get a list of the dates picked with tick-boxes etc. and you can disable certain ones?
