MARK beginner - density and tag loss

[gigio]

hi,
I'm a new Program MARK user and 'I've some question about...

the first question is on the tag lost adjust: how can I do it?

the second is about the density-dependence: is there an automatic way to calculate survival and recapture (for example) parameters depending on density?
i've done it considering density as an individual covariate.

i hope you'll have some suggestions...thank you very much!!
