[Jobs & Experts] Offer dropdown of job skill tags in expert profile entry

In Jobs and Experts, Profile entry, Add Skills, there is a textbox for free-form entry for all skills. I\'ve carefully entered a lot of skill tags and related descriptions. I expect job seekers and job providers to use these industry-specific tags to closely match skills with positions available. I don\'t want to prevent either side from using custom qualifications, but I will discourage that to some extent.

This request is for Settings to offer a selector for one of the following:
1) Freeform text entry (current default)
2) Dropdown with data provided by Job Skills Tags
3) Combobox, combines #1 and #2
