Is posible to do a random respawn in CSDM??

[RPG]

Yes.
csdm.cfg

;Sets the spawn mode.
; "none" - users spawn at normal map spawn points
; "preset" - csdm_spawn_preset.amxx required, uses predefined spawns in config files.

spawnmode = preset

No. CSDM wasn't designed to switch players beetwen teams. You may need a separate plugin for that. Ask at Suggestions/Requests forum.
