Gaining new skills requires significant expenditure of time - about a week for the first skill point and no more than 5 skill points per month for existing skills, per p. 153. Being forked for a week or longer imposes a -30 modifier on the merging test with "minor memory oss[sic]" and 5 Stress damage if you [i]succeed[/i] on the test; failure causes severe memory loss and d10+6 Stress, which is a pretty-much guaranteed Trauma. (An argument could be made that skills can be learned in under a day using VR time compression, but I would counter by saying that fork time should be counted as the longest subjective time experienced by any involved fork.) So, from a strict mechanical standpoint, I'd call it a non-issue on the basis that someone trying to fork, buy up skills, and re-merge will be quickly driven insane by the stress of merging such different forks. From a gamemastering standpoint, I would say something like, "No, Rez points are not duplicated when you fork and you only gain Rez points per character, not per fork, so forks can't gain their own Rez points unless they first become NPCs. This is because getting more Rez points by forking would be abusive and break the game system." If they decide to do it anyhow, I'd go with the highest, on the basis that, just like the character only gains Rez once, he also only spends it once, so any spent Rez should benefit him long-term regardless of which fork makes the expenditure. This also means that, if three forks all study the same skill, improving it by 1 only costs 1 Rez point total, not 1 Rez per fork.
