TikiWIki Beginner
I am new to tikiwiki and have some questions that might seem kind of stupid, but I have not been able to figure these things out. I am trying to create a database of best practice documents, templates, and forms for my co-workers and I to use. I have a lot of documents that I would like to upload to my tikiwiki page so that we can search for and view them as needed. I have been able to upload files by attaching them with the attachment button at the bottom and through the my files section. I have done this as both an admin and a user. However, when I go to look at the documents it opens them up in word, which makes sense because they are attachments. How or where can I upload them on the site so that this will not happen? I also want to be able to make abstracts for the documents and set keywords that they can be searched by. I have put some of the documents in as articles and done what I want with some degree of success, but, I would rather be able to do this by just uploading files instead of copying and pasting the documents. I want to create a database where my co-workers and I can easily search for, retrieve, and add documents that we can use for reference.
So, my main questions are:
1) Where and how can I upload documents so that they can be viewed as part of my tikiwiki site?
2) How can I then add an abstract for people to see before they bring up the full document, and how to set keywords for search?
3) I also want my users to be able to post documents that the other admins and I can then approve and modify as needed. How can I do this?
These are the big questions I have right now. Please let me know if you need any more detail on what I am trying to do. Like I said I am new to this and could use all the help I can get. Thank you very much
