my VM 1.1.4 with J! 1.5.15 and SI 5.1.2 seems to be working (the captcha image appears on registration, reminder, etc... but i've yet to try it out).
i can't figure out how to introduce the captcha on the module vm_login though!
i've applied the same patch supplied by Walter Cedric for the standard J! login module, but it has no effect.
has anyone got any idea? it seems a shame to have gone all the length to integrate SI into VM just to leave out the modules! i bet there's a solution...
