Linking to channel page I'm just getting started with Craft. My problem is that I'd like the user to be able to change the location of call to action buttons on the site. Instead of allowing them to enter any URL, it would be bit nicer to let them select the related entry. 

I can use the entries type, but it won't allow me to select channels. How should I proceed? Create a single section that displays the channel entries so that I can link to it?

Are you trying to select the actual Channel itself? (like the News / Blog).


Trevor Davis' handy Listing Section fieldtype could work here. 
If you want more control as to what is shown on that channle's "index" page (intro blurb, featured entries, etc), as you mentioned, just create a single that maps to the index page of the channel. Craft's routing is smart enough so when you go to /blog/ (for example) it'll route to the entry first.
