Nation URL in Contact Detail

I see that in https://forum.thenorthpacific.org/account/contact-details, the nation URL replace space with "+", not "%20" or "_". This cause the url often link to my nation. For example:
Contact detail URL: https://nationstates.net/nation=inven+in+tnp
NS url: https://nationstates.net/nation=inven_in_tnp or https://nationstates.net/nation=inven in tnp

This is a problem because I cannot go to a TNPer's nation page directly, I have to search for it

The field works, it just requires the use of underscores for names containing spaces. (i.e. Inven_in_TNP)

I've edited the instructions for this field to include this step.
