Found fix for my first question. To remove "Search by name" or "Search by Username" locate the file /ow_system_plugins/base/views/controllers/user_search_index.html

find this line of code near bottom:

"<div class="ow_right ow_narrow">

        {form name='DisplayNameSearchForm'}

            {block_decorator name="box" addClass="ow_center" iconClass="ow_ic_lens" langLabel="base+user_search_display_name_search_label"}

                <div class="clearfix ow_smallmargin">

                    {label name=$displayNameQuestion.name}

                    {input class="display_name_input" name=$displayNameQuestion.name}

                </div>

                {submit class="ow_txtcenter"  name='DisplayNameSearchFormSubmit'}

            {/block_decorator}

        {/form}

    </div>"

and delete, save, upload.

Tim,
>>Second question is how can I edit the users profile page title.

It is under Languages in admin panel. Search by the "username" keyword.
Text key you are looking for is: {text key='base+profile_view_heading'} ( yoursitename.com/admin/languages?search=username&page=2 )

Great. Thank you Aliia.

Also, is there anyway to set the lifetime of a member login time? Where the script will log an inactive user out after (example) 15 minutes?

lifetime of a member login time?
set your site cron job or search the topic about this...

Thanks cit24..
