I suspect that I'm focusing on the wrong problem so I will first describe what I think the problem is before presenting the possibly suboptimal solution I envision.
Currently my co-workers commit their code changes only after loooong periods of time in huge chunks with changes spreading all over the project(s). That's progress I guess, because not long ago they just put .zip archives on some network share. Still, merging is a nightmare - and frankly I've had enough of it. And I'm also tired of talking and explaining and begging. This just has to stop - without me constantly being "the bad guy".
Since there seems to be no awareness of and/or no interest in the problems and I cannot expect any efforts to last longer than a few days ...strike that, hours, I'd like the subversion server to do the nagging.
Am I way off-base here or am I looking at the wrong problem? It seems like I'm missing something, and I think I'm asking the wrong thing by looking at tools to solve my problem.
Should I be looking for a tool to solve this problem or what is it I should do to fix this?
