There are a couple of smf mods for this, I would like to know if those options could be added as an addon for Elk.
For the location I could add a custom field and move the data from "Location" to my custom field. As a custom field I could set it as visible under avatar. For the date there is no custom field that could be set as date
Interesting, in fact I always felt the custom fields are a little "limited" in terms of type of fields, dates, multiple inputs, multiple languages (why not), etc. are not currently possible, but would be at least nice to have. I think.
