When Federico Kereki introduced XHTML tables ( Adding diagrams to your problems) to Perplexus he gave us a tool which allowed us to "bug levik" less. Those tables were generated via OpenOffice Calc.
The data was a collection of classes bundled within a style block along with an HTML table heavily padded with attributes. It took a little care in edit to make these usable at Perplexus.
NOW OpenOffice has made this much easier. The data is still a set of HTML tags (a STYLE section still exists - for my first project it does not seem to have relevance, but I won't dismiss it completely). Each of the TD tags has its own STYLE for its attributes but these should not be edited without due knowledge.
While MEMBERS are unable to post problems directly using this technique they should not feel discourage. The PROCESS requires:
1. Create and edita spreadsheet in Calc applying whatever formatting is needed.
2. Save the file using the ODS extension. This enables you to return to execute any further edits as may be required.
3. Resave the file again but using the HTML option.
4. Open the HTML file in some text editor and add whatever problem body text, including TAGS, that you wish.
5. Create and Submit your new problem in the standard way except that the you only add something as body text merely as a placeholder.
6. Forward your HTML file (or whatever lies between the BODY tags) and the problem's pid="num" to a scholar.
7. Once in place any further edits must be done by a scholar on your behalf.
