Designing intersection flows

There is a potential problem if forms are involved and users have to choose between this and that in order to proceed. We should be alert if two or more forms are present on the same page, i.e. if there are two or more sets of input fields with each their submit button - especially if they are placed close to each other and if they work in a similar way.

There seems to be two ways to eliminate intersection problems. If possible, get rid of options which aren’t mission critical. If this isn’t possible, combine the options into one clear dialogue.
