also your time line needs other smalling builing blocks for the builder to move stuff around. or
you have to allow data entry from where ever those data screens are available. currently yout timeline can only be accessable by profiles. and the accounts section does not allow posts. are you trying to confuse beginner users? lol. KISS (keep it simple stupid)
now i know i have two pages of time line data. and that little time range slider on top seems to be stuck on the current posts no matter where i shift it. check your variables and the code that makes that timeline with the timeline range slider. it's a really good option especially if it goes to the right day on the slider.
