7 archive boxes seems like a lot of paper to me! More than I would have space for, anyway!
Like Martin, I suspect that you could pass on and share the results of your research more easily with family members, other researchers and organisations if it was 'digitised' as much as possible:
1. digitising any content (documents, notes, photos, certificates, etc.) that isn't yet in a digital form
2. making the content available in a way that different people can find the information they're interested in.
You could upload a Gedcom file (you can export one from tribalpages) for free to other websites like Ancestry and FamilySearch. Your basic tree data would then be available to a wider group of family researchers than on TribalPages. Message boards are useful too.
Software like FTM 2017 and RootsMagic7 is useful for importing Gedcom files, adding digital media and links to online documents, notes/stories, and publishing everything to Ancestry, FamilySearch or your own website.
Having a website (too) might give you the most flexibility in 'telling your story' and making documents available. You could provide links to longer (PDF) documents stored either on the website or stored separately 'in the cloud'. You could include links to your on-line trees and include a link to your website in your on-line 'profiles'.
As Martin suggests, it would be ideal to enlist the help of a internet-savvy student/volunteer in this.

When you have backed-up copies of your 'digitised archive', you can better assess which documents have value in their current physical form and which ones could be removed (and printed out again from the digital version if necessary).
