My guild has always, in any MMO, had fun doing activities in the game that are off track from the game design. For example, we used to enjoy racing low level characters through high level zones to see who could evade the mobs the best and generally allow the people to relax knowing that there was no consequence to their actions.
SWtoR does not currently permit something like this to happen due to the restriction of not being allowed to board someone elses ship without owning your own ship first.
Can you please change this mechanic because the ability to organise 'fun' events is something ours, and I'm sure many other guilds would enjoy, after all, I'm sure Anakin didn't own a starship when he was taken to start his Jedi training ;-)
