A few Questions about Jobs & Expert Plugin modification

Hello,

I'm modifying your plugin to our needs, so i have some questions for you, if you can help me!

1. When an expert opens a Job Listing, and a second expert opens the same job, only the first one has the ability to Contact the author of the job. How can we disable this?

2. How can i change the "Contact" button text in job listing page?

3. In Job listing page, how can i remove the links from the Skills?

4. In Experts listing page, is there any option to display only the Name of the Expert and hide the Surname?

5. Where can i find and change the text of "Tag Line" modal box?

Thanks in advance
